“Rules of Engagement” on CBS at 8:30pm ET. Sometimes I think my pop culture knowledge is pretty complete. I’m aware of the general ideas of most tv shows even if I don’t watch them personally, I know my actors and actresses pretty well, and by and large I get references that people make. Then I realize there are shows like this on the air, that are in their seventh season and that I have not ever seen a single episode of and I have to consult Wikipedia to remind me which washed up star is the lead. (David Spade, for those wondering.) It’s humbling in a way.

“Bunheads” on ABC Family at 9:00pm ET.

“The Following” on Fox at 9:00pm ET. I had been trying to give this a fair shake, and then I missed last week’s episode for reasons I can’t remember now and went to watch it on Hulu. Only to remember that Fox only posts shows on Hulu a full week after they actually air. So I guess Fox doesn’t actually want me to stay caught up on their shows in the span of time I’m mostly likely to care about doing so (one to two days after it airs) so this show can go in the “didn’t care enough” pile of discarded television.

“RuPaul’s Drag Race” on Logo at 9:00pm ET.

“Teen Mom 2” on MTV at 10:00pm ET. Eighth season premiere. Eight seasons, you guys. Although I hear the birth rate among American teenagers is dropping, so maybe this show should be compulsory viewing in all middle and high school health classes. “We can tell you all the reasons this is a bad idea, but how about we just watch this 16 year old change an overflowing diaper at 3am while her C-section stitches are still healing! Have some condoms. Have lots.”
